It’s great to hear, that this is technically viable. I really hope, this will be added in the near future of Gnome.
And to make it perfect, it should also be possible to insert not only line-breaks, but also the content of the clipboard on a certain position and to define, where the cursor should be located.
An example for an use-case:
I often have to reply to many people - sometimes in a word-processor or editor, other times in different mail-software and the next time in a web-frontend in different browsers.
It would be easy, if a shortcut like e.g.
would be replaced by (special input in square brackets)
Dear Mr. [clipboard],[linebreak]
So that I can start typing directly on the cursor position without positioning the cursor by hand and that I don’t have to type all the rest manually every time. And then I get:
Dear Mr. RECIPIENT-FROM-CLIPBOARD,
(And the same with
for a female recipient:
Dear Mrs. (and so on)
And I’m sure, there are many more usecases, where this feature would be very useful to make things easier and faster.
I know, that many mail-clients offer templates or that there are e.g. Thunderbird-Plugins, that offer exactly this features (and even more). But to have this systemwide in every mail-client, every webbrowser, every editor and every word-processor, you need this feature integrated into the system on system-level.
This would be a productivity-feature, that would let Gnome stick out.
